I was used to run Ollydbg under Windows2000 and all went fine. Now I use Ollydbg 1.09c under WindowsXP Pro SP1a and I *always* receive the following error message when I attach to an executable (and sometimes when breakpoint is reached):

"In order to perform action that is not supported by OS, Ollydbg has injected short piece of code (...), but received no response within 5 seconds. (...)"

How can I avoid this message? Should I change some settings? Update DLLs?
Please help!

you can disable from options "allow code injection winproc ..."
... on my XPSP1a works fine.

I already tried this option but it doesn't help so I deleted ollydbg.ini then I added each option carefully. I left only SSE/AMD/registers and it works.
